Rebirth in 70, I Have a City in the Last Days

The heroine is not an absolute bad person or a good person. She is an egoist but has three views. Yu Nianxi was pushed to death by her step-sister in her previous life and traveled to the future, where she had just graduated from college and ushered in the end of the world. The base is facing the evacuation of the destruction organization, and the plane she is traveling on crashes, and when she opens her eyes, she returns to the 1970s... I thought she was lucky to be back here, and didn't expect to be able to travel through the apocalypse. In the city where she lives at the end of the world, she is the only one left alive... In order to live a better life in the 1970s, I talked to people and told ghosts to expand my network of contacts. Based on the trend of history, she seized every opportunity and still managed to make a fortune.
